[0026] The overall effect achieved by the entire Embodiment 1 is that when the driver blows air into the blow tube 2, the gas enters the blow tube 2 and passes through the detection holes 4 into the alcohol sensor 5. The alcohol sensor 5 can sense the alcohol concentration, facilitating alcohol testing. When the alcohol sensor 5 is damaged and needs to be replaced, the pull plate 15 is pulled, causing the sliding plate 12 to drive the limiting block 13 to move into the empty slot 10, thereby releasing the restriction on the plug 8. Subsequently, the plug 8 is pulled out from the slot 6 to complete the disassembly of the alcohol sensor 5. When reinstalling a new alcohol sensor 5, first pull the pull plate 15 to cause the sliding plate 12 to drive the limiting block 13 to move into the empty slot 10. At the same time, the return spring 11 starts to contract under the extrusion of the sliding plate 12. Then, the plug 8 on the alcohol sensor 5 is inserted into the slot 6, and then the pull plate 15 is released. Under the elastic force of the return spring 11, the sliding plate 12 drives the limiting block 13 to squeeze into the limiting groove 9, thereby limiting and fixing the plug 8 to complete the installation of the alcohol sensor 5. It is convenient to use and saves costs.
[0027] Embodiment 2: As Figure 1 - Figure 6As shown, one end of the blowing tube 2 passes through the tester body 1, an external thread 16 is provided on the outer surface of the blowing tube 2, a connecting tube 17 is provided on the outer surface of the blowing tube 2, one end of the connecting tube 17 is fixedly connected to a blowing hood 18, an internal thread 19 is provided on the inner surface of the connecting tube 17, the internal thread 19 and the external thread 16 are meshed with each other, a display screen 20 is provided on the front side of the tester body 1, a button 21 is provided on the front side of the tester body 1, a flip cover 22 is provided on the front side of the tester body 1, one end of the flip cover 22 is hinged to the tester body 1, and the other end of the flip cover 22 is covered with the tester body 1, the display screen 20 is electrically connected to the alcohol sensor 5, a protective plate 23 is fixedly connected to the outer surface of the tester body 1, one side of the limit block 13 movably passes through the empty slot 10 and extends into the slot 6, and one side of the pull plate 15 is fixedly connected to the slide plate 12.
